+    t1800: correct test to handle Cygwin
+
+    The OS-specific code in start_command affects Git for Windows but not Cygwin;
+    Cygwin behaves like general *nix systems for these purposes.  As such, when
+    checking for the error from running a script with a bad shebang, only expect
+    the Windows-style behaviour if the prerequisite MINGW is set, rather than using
+    WINDOWS which is set for both Git for Windows and for Cygwin builds.
